HULL, OF DAYTON, OHIO,A ASSIGNOB 'IO FRIGIDAIRE CORPORATION, OF 1 DAYTON, OHIO, A CORPORATION OF DELAWARE mmennarime APPARATUS L allpncationmea Api-i130, 1329. lser-iai no. 359,395. ff d This invention relates to refrigerating apparatus and especially to beverage cooling and dispensing apparatus having a container discharging a beverage into the usual cooling chamber.

An object of the invention is to maintain -the container having the supply of the-drink having a refrigerant liquifyin'g unit therein such as is fully disclosed in my corpending application, SerialNo. 289,549. A base 11 of the beverage cooling section rests upon this main base and supports a plurality 55 of outer side panels12 enclosing insulation panels 13 such as corkboard, a frame Work lto be dispensed in a cool state as well as the\.iudicated at 14, and an inner lining 15- 0f beverage chamber.v 10 A further object is to produce a visible frost about the container in order that the coldness of the beverage may be appreciated. More specifically, the `invention contemplates placing a frost producing means aboutXthe 15 bottle or other container so that the customer may readily see that the beverage Withdrawn from the dispensing apparatus is cold.

Further objects and advantages of the present invention will be apparent from the following description, reference being had' to the accompanying drawing, wherein a preferred form of the present invention is clearly shown. In the drawing: v p Fig. 1 is a viewpartly in elevation and partly in cross section disclosing beverage cooling and dispensing apparatus embodying the invention.

Fig. 2 is a similar view of a modification of the apparatus of Fig. 1. y One'of the popular types of beverage cooling and dispensing apparatuses has been the type having an insulated beverage chamber with a supply container generally in the form of an inverted bottle or demijohn, the major portion .of which has been exposed to the warm air of the store or other locality. Ac-

cordingly, this invention contemplates thel provisionof cooling means about the con- 40 tainerv and especially such cooling means as will produce afrost about this container. In vthis manner the beverage is'pre-cooled before it descends into the storage chamber and" especially has the advantage, from a, sales pointof view, of calling the customersattention to the cold state of the beverage by means of the covering of frost over the exterior of the container. v

` In Figs. 1- and 2 are disclosed a base 10 for 5 beverage cooling device, such base preferably the beverage chamber orA compartment 30. The inner sides ofl thevouter panels and the outer sides of the inner panels and the cork and cracks therebetween is thoroughly coated with a bituminous cement. A faucet 16 extends from the beverage chamber thrujto-the outer panel, preferably thru a reinforcing 65 piece of wood 17. o Insulation 18, preferably of hard rubber, covers the upper edge of the walls of the chamber and supports an inner cover 19 thereon. The cover 19 has a collarl 20 with another insulation collar 21, prefer- 70 ably also of rubber, for supporting the'container 22. This container is preferably of the bottle type and the form disclosed is generally referred to as a demijohn.

In Fig. 1 a transparent glass '2,3 surrounds 'I5 a part of the bottle and has an insulating collar '24, preferably of hard rubber, inserted between it and the upper portion of'theiuverted bottle.

In Fig. 2.the invention is modified by having the transparent glass cover 33 enclose the inverted bottle 22. The vtransparent glass covers 23 and 33 restv upon the rubber insulation 18. In'either modiiicationthe bottle 22 can be readily removed. In Fig. l-it can be withdrawn vertically upward and in Fig. 2 it can 4belikewise withdrawn vertically upward after the removalof the cover 33.

The liquid refrigerant supply line 25 lextends thru one of the'walls of the beverage 90 i chamber to anl expansion valve 26. This line preferably extends from a refrigerant liquefying unit in the base 10 referred to above. 'I A. conduit 27 extends upwardly from` expansion valve 26 to a. plurality of coils 28 about the 95 inverted bottle.e The conduit may then de scend into the .beverage chamber where it may have -a further plurality of coils 29. F mv .these coils there may be asuctionline return for the refrigerant by meansfof the conduit the exterior of this container.

and shape o f the chamber and the container may be made.

It will vthus'be noted that the liquid refrigerant will rst be sent around the container and will provide frost producing means for It will be necessary that a certain amount of moisture be contained in the space enclosed by the transparent covers 23 and 33in order to produce l this frost. Accordingly, the connection of these covers withthe insulation 18 is not made so tight as to shut olf this moisture. Ifdesired, a certain amount of moisture may be placed on .the cover 19 in order that a produc-A tion of frost may be insured on the outside attention to the fact of the bottle 22. It is not desired, however,

'to produce such a heavy frost that there i-s f in 40' g any danger of reezingthe contents of the bottle. It is desired, however, to produce a suiiicient amount to pre-cool the liquid in the bottle, and especially to call the customers that an efficient cooling means has been installed in the beverage dispensing apparatus.

Accordingly there has been disclosed a beverage cooling and dispensing apparatus hava pre-cooling and frost producing means applied to the container discharging into the beverage compartment. While the form of embodiment of the inventionas herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows: l

1. A beverage cooling and dispensing apparatus comprising an insulated beverage chamber, a removable beverage container supported in an inverted position above said chamber and having its opening projecting into said chamber, mechanical cooling means about said container and mechanical cooling means in said chamber.

2. A beverage cooling and dispensing apparatus comprising an insulated beverage chamber, a beverage container having an opening into said chamber, an expansion coil paratus comprising an about said beverage container, an expansion coil in said chamber, and transparent means enclosing said first named expansion coil.

3. A beverage cooling and dispensing ap- 'insulated beverage chamber, a removable demijohnhaving an opening projecting into said chamber, cooling 2l. A beverage cooling `and dispensing ap- I i paratus comprising an insulated beverage chamber, a removable demijohn supported 1n ,aninverted position above said chamber and having its opening projecting into said chamber, cooling means about said demijohn, said demijohn being removable independently of said cooling means, cooling means in said chamber, and transparent means enclosing said first mentioned cooling means. j

5. A beverage cooling and dispensing apparatus comprisin an insulated beverage chamber, a cover or said chamber, a beverage container supported by said cover and having an opening projecting into said cham# ber thru said cover, la frost producing coil about said container and a cooling coil in said chamber. v
